'77o all whom t may concern:

' 'Be it known that I, WALTER II. PRUEEER, .t citizen'of the UnitedStates, and resident of the city of Providence, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvementsv in Bracelets, of which the following is aspecification.

This invention relates Ato flexible bracelets of the non-extendible typeand has for its object to construct such a bracelet of aseries of unitseach comprising a box shaped member the same being connected into aflexible chain adapted to be used as a bracelet or other similar articleof jewelry.

A further object of theinvention is to provide an H-shaped link forconnecting these box shape membersyieldably together.`

The invention further consists in the provision of a closing plate forthe back of the box and in rolling the edges of the box inwardly andover onto the plate to permanently lock and hold the whole in position.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claim.

In the accompanying drawings:

Fi re 1- is a side view of my improved brace et.

Fig. 2- is an ed e view showing the series of the box mem ers connectedtogether.

Fig. 3- is a face view yshowing a blank as cut from sheet stock into ashape fromY which the box is struck.

Vso

Fig. 7- is a perspective view showing the back plate which fits into andis secured in the box link.

Fig.y 8- is a sectional elevation showing a number of the box members asconnected together by H-shaped links also showing the back plate asbeing secured in the box by rolling they edge of the latter over ontothat of the former.

Fig. 9 is an enlarged' view of the snap catch which releasablysecuresfthe opposite ends of the bracelet together.

Fig. 10*y is a sectional'elevation showing the snap as connecting thetwo adjacent links together.

Fig. 11 -s'a perspective view illustrating Y the construction of theendof the box show'- ing the lip portion which is releasably engaged bythe shoulders of the'catch member let.`

Referring to thev drawings y10 designates thev blank vas cut fromsheet'fstock from which the box member is drawn up. This blank may bemade of any suitable material, but bracelets and' chains of thisconstruction are usually made of a heavy rolled plated stock. After theblank has been cut from the sheet metal, it is then struck and drawn upinto boxform as illustrated in Fig. 4 the corners being notched as at 30to permit of the edges of this box being subsequently rolled overinwardly.

After the box has been drawn up into as at 13 inwardly from their margin14.

The connecting link member 15 is preferably formed in the shape oftheletter H, the cross bar portion V16 being of a width to be passed intoand fit loosely in the slot 13 and the legs 17 and 18 are designed topass into adjacent boxes and abut against their inner end walls thusloosely connecting these box members together.

In order to close the backof this box, I have provided .a plate 19 whichis of a shape to fit into the-box along the dotted line 20, see Fig. 6,and after being positioned therein the edges 14 and 31 of the box arerolled over inwardly onto the plate thereby providing a secure fasteninfor holding both the back and the H-link rmly in their respective boxes.

By this construction, it willtbe seen that the base metalabout the edgeof the back is turned inward by the rolling of the edge, so that onlythe outersurface of precious metal is exposed.

In order to connect the adjacent ends of this chain or bracelettogether, I have prol connected to the opposite end of the bracethedesired form the` end walls 12 are slotted vided a catch member 21, seeFig. 9, having its body portion formed of spring metal and folded overand back upon itself, one end of the body portion is provided withrecesses 22 cut inward from its opposite edges, thereby forming a heador leg 23 to engage the inner wall of one of the end links and alsoproviding a bar portion 24 which enters the slot 13 in the end wall ofthe box by which construction this catch is connected to the said boxlink. The'opposite end 25 of the body portion is provided with a presserextension 26 turned outwardly and the shoulders on each side of thisextension are adapted to engage the end walls 27 of the end link 28 sothat when it is desired to release this catch it is only necessary toforce this presser member 26 inward and the shoulders 29 are disengagedfrom the edge 27 of the link 28 permitting this catch to be readilywithdrawn and the chain or bracelet separated.

By my improved construction of chain or bracelet the box members may bemade of inexpensive plated material and when completed none of the basemetal is exposed and these box shaped links are readily conneoted orassembled into a series of links connected together by means of a simpleform of H-shaped link which permits the lnecessary and desirable amountof flexibility to the chain.

I have shown and described one way of constructing the links of myimproved box chain or bracelet but the detail of this construction maybe varied without departing from the spirit and scope of my invention.

I claim:

A bracelet constructed of a series of units, each unit comprising a bodyformed of a single piece of sheet metal having portions bent at an angleto provide side and end walls, said end walls being slotted from theirmarginal edges, a cover plate, the marginal edges of said kside and endwalls being bent over said plate, and links connecting contiguous units,each link .being headed and provided With a shank passed through theslots of contiguous end walls of adjacent units.

In testimony whereof I affix my signature in presence of two Witnesses.
